Dennis,

I also got rid of the Deadman valve after fighting with it for a couple of days. Not only wears the tips out but also the metal plate you hope to stop the media with.

Since I recycle the glass a few times it ends up getting very fine and powdery. So I am going to experiment with the coarser grit once I use up what I have.

I wish I could recycle my media But I am blasting outdoors I started to build a Blast booth Put in a Cement pad. But that's as far as I got.
Some day i will start on it again but it's pretty far down on my Priority list right now.
I started with a Big blue Tarp and the wind out here got it.

Still blasting metal when I get some time to work on the car.
The 20/40 grit crushed glass is a little too coarse at first. It does break down though and about the third recycle begins to work very well. I plan to order the 40/70 grit from now on though.

Firewall looks to be very solid:

Just to see what the heavily rusted passengers floor pan looks like I blasted away the heavy flakes. As they came off more and more holes appeared. A little hard to see in the picture:

Worked my way down the door jamb and too the pans under the rear seat. This area seems to be quite solid as well:

The big debate I am having right now is on whether to remove the quarter panels and see what kind of rust is hidden there.

There is going to be Rust back there for sure BUT you should be able too see how bad it is by looking down between the where the rear window was this allows you to see how bad or heavy it is in front of the wheel well as far as whats under the Trunk drop off there should be Plugs you can pull and get in there with a Cheap bore scope from harbor fright OR one of these:

I used one last week at work instead of an expensive Aircraft engine Bore scope I was Very impressed with it especially for the price! lets you get in there and see things without tearing something apart. the company that makes them has several different models to chose from.

Just me but if its not as bad as the floors I would just treat them with Phosphoric acid and coat with epoxy after cleaning I know the subject is taboo with you BUT When is deep enough deep enough? The car does have a certain Dollar value attached to it when completed no matter how much and time and money is invested you know this.
